MobiCloud: Performance Improvement, Application Models and Security Issues

Recent years have seen an exponential increase in cloud computing for services such as high computational capabilities, vast storage, applications etc. that they provide. Moreover, today’s world is a constant shift from desktop or laptop devices towards handheld smartphones because of the wide range of applications that are supported. This paper discusses the present state of cloud computing for mobile, termed as MCC or Mobile Cloud Computing. This paper also explains the MCC architecture, and the various existing application models, namely Energy and Performance based, constraints based, and Multiple Objectives based models and their examples. We also identify the research gaps in this area which cover the need for standardization of mobile cloud execution platforms. We further point out the vulnerability smartphone clones, and the need to address the privacy issues and security attacks against the user.
